Aseptic necrosis is a bone condition caused by poor blood supply to an area of bone, leading to localized bone death.
Aseptic necrosis begins as a painless bone abnormality and may not cause pain. Pain in the involved bone may develop over time, especially with use. For example, if a hip joint develops avascular necrosis in the ball of the hip joint, pain can be felt in the hip, buttocks, or groin, and limping may result.
Causes of aseptic necrosis
Trauma to the bone, damage to the blood vessels that supply oxygen to the bone, poor blood circulation to the bone, abnormally thick blood (hypercoagulable state), atherosclerosis, and inflammation of the blood vessel walls (vasculitis) can cause aseptic necrosis.
